but it's a bit culture specific. German children TV has a pretty long running show that does "how it's made" for children + small, probably only 5 minute animated stuff and at the end a puppet/animated show of this old bear telling his grandchildren weird made up stories that he claims are totally true.
Obviously this is feature length. So in this movie, his old archrival shows up, and kidnaps the kids. Grandpa has to roll up his sleeves, and go save them. And of course do wild stuff that sounds totally made up when he tries to tell the kids later.
Fanny and Alexander. Also Bergman, also a masterpiece. Period dram about two siblingsa, is available both as a movie and a mini series, the mini series is of course longer, but the version I recommend, since it's easier to take breaks, it's awesome, but it's pretty dark
"Gentlemen of Fortune" is a hilarious movie where a school principle is chosen to infiltrate a band of crooks due to him looking exactly like their boss.
